Specification of Letters Patent.

latented April 27, 1909.

Application led January 13, 1908. Serial No. 410,580.

To all whom 'it may concern:

Be it known that we, WILLAM ROBERTS and CARROLL ROBERTS, citizens of theUnited States, and residents of Springfield, in the county of Clark andState ofV Ohio, have in vented a new and Improved Pole, of which thefollowing is a full, clear, and exact description.

4This invention relates to poles and'more especially such poles'as areused for stringing electric circuit wires and the like.

An object of this invention is to provide a pole which is so constructedthat the parts can be easily replaced or repaired.

A further object is to provide a pole which can be braced unequally onopposite sides, when for example, the pole is inclined on curves or thelike.

A still further object isto provide a device of they class describedadapted removably to carry a mast and cross-arms 'upon which the wiresare strung.

Another ob'ect of the invention is to providea pole comprising a columnarranged so that it can be braced on all sides andhaving means forremovably carrying the mast and cross-armsfforv supportingwires, the olebeing firmly mounted upon a suitable ase of concrete or the like.

The invention consists in'the construction and combination of parts, tobe more partic- .ularly described hereinafter and particularly setforthin the claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorrespondingr parts in all the iigures', in which-` Figure 1 is avertical section of the device having parts lbroken away and showing amethod of bracing the pole and supporting the same on a concrete base.Fig. 2 is an enlarged cross section on the line 2 2 of Fig. 1; Fig. 3 isan enlarged cross section on the line 3-3 of Fig. 1; Fig. 4 is anvenlarged cross section on the line 4-4 of Fig. 1; Fig. 5 is an enlargedsectional view showing the method of attaching the pole guys at theirupper ends; Fig. 6 is an enlarged sectional view showing the methodemployed in supporting the guys at a point intermediate of the ends;Fig. 7 is an enlarged sectional view showing the method of securing theguys at the base plate; and Fig. 8 is a perspective view of the poleshowing the same supporting telegraph or other wires.

Before proceeding to a more detailed description of our invention, itshould be understood that we provide a metallic pole havingsupportingrods or guys and provided with a removable mast which is adapted tocarry either metal or wooden cross-arms for supporting wires. Thesesupporting rods or guys are of advantage, especially on curves orgrades, where some of them may be of greater strength or ,adjusted togive the .greatest resistance to displacement or sagging to retain thepole in an operative posi tion. A pole sup orting base of concrete isemployed, which liolds the pole out of oontact with the ground andthereby serves both to insulate the pole from the ground and to preventits base from rusting. The pole can easily be separated into itscomponent parts or members. This naturally proves both an advantage andan economy, for should a pole become damaged either in a wreck orthrough Vthe eliects of the weather or other destructive agent, torepair it, it is simply necessary to replace the damaged section. Inshipping, the pole can be packed in a much smallei` space than one whichis not separable into parts.

Although in the preferred form our pole is used for Stringing tele honeand telegraph wires, it may be use in connection with traction linesusing overhead wires, without any material change in construction, orfor other similar purposes.

Referring more particularly to the drawings, 1 represents the poleproper, which is fashioned from any suitable material, such as cast ironor the like. A metal base plate is mounted u on a concrete base 6 ofcommon or preferre form, and is secured to the latter by means ofbolts'7, the Shanks 9 of which are embedded deeply into the concrete andform a reinforcement therefor, as shown in Fig. 1, While nuts 8 serve tosecure the base plate rigidly in place. The top of the concrete baseprojects somewhat above thel ground. The shanks 9 may be suitablyfashioned to give the greatest resistance to dislodgment under thestrain incident to the swaying of the pole; for example, they may ybesinuous in form as is shown in Fig. 1. The

4*? constricted.l ntermediate of the ends ofcircular sections 12, eachadapte partly to clamped in position.

embrace the column and each having a double flange 13. These flanges,when the sections 12 are in position, present adjacent faces so thatthey may bcsecured together by means of bolts 14, or the like, passingthrough the openings 15 provided therefor.

The edges ofthe flanges 13 are recessed to rei ceive a plate 16 havingan annular rim 17 the latter being encircled by a securing ring 18. Theplate 16 is integral with the sections 12.

Arranged at the upper end, 4b of the column, and fashioned to receivethe same, is a head 24, constituting a socket. The head 24 has acircular flange 25 at the upper end. A split collar 19 is mounted on theflange 25 and has a flange 23 which rests upon the flange 25, near theouter edge of the latter. The split collar has ears 20, which haveregistering openings 21 to receive the clamping bolts 22. The mast 2ahas the butt removably arranged within the collar 19 and The arrangementis such that the base of the mast rests partly upon the up er face ofthe flange 25 as is shown most c early in Fig. 1. The flanges 23 and 25have registering openings 26, to receive bolts 27, by means of which thecollar 19 is secured in position upon the head 24. The mast 2a ma be ofwood or any other suitable materia and of taperedv or other form,adapted for the purpose.

In the referred form the cross-arms 33 of any suita le material, such aswood, metal or the like, are used to support wires and cables and aremounted in grooves and secured in position by means of bolts 34.

Guys 28, fashioned from any suitable material, brace the pole inposition. The lower ends of the guys are secured to the base plate 5 inany suitable manner, for instance in a recess 35, as is shown in Fig. 7.In this case each of the guys is provided with a laterally extended head39 at the lower end which seats in the recess 35. The base plate has anopening 40 to receive the guy 28. At their upper ends, the guys passthrough openings'29 inthe flange 25 and are suitably threaded to receivesecuring nuts 30 and 31 at the upper and lower sides respectively of theflange 25. Each nut 30 is countersunk in a recess 41 of the flange. Fora central support, the guys pass throu h edge recesses 32 1n the rim 17,and arehel in ositionbythesecuringring18. By suitabl adliusting the nuts30 and 31, the guys can, be len thened or shortened with res ect to theco umn, to brace the pole.

aving thus described our invention, we claim as new and desire to secureby Letters Patent:v
